For example, there are an article foo photo XYZ 1, XYZ 2 and XYZ 3 explaining how to do great photos in low light for all the cameras XYZ. The explanation is exactly the same for all these cameras.

To be more featured as SERP featured (position 0 on SERP), should I have one article by device (one for camera XYZ 1, one for camera XYZ 2, and one for camera XYZ 3)  ? Only the title will be different, any other content will be exactly the same.

In that way, the article could be an exact match of what the user searches for. But all the articles will be duplicated 3 times.

For example, I have an article about how to take photos in low light. This article is applicable to several cameras. The explanation is exactly the same for all these cameras. I currently have a single article titled: "foo photo CAMERA1, CAMERA2 and CAMERA3".

To get better rankings (top positon) for the various cameras, should I copy the same article for each device? One for CAMERA1, one for CAMERA2, and one for CAMERA3)? Only the title would be different, any other content will be exactly the same.

In that way, the article could be an exact match of what the user searches for. But all the articles will be duplicated 3 times.
